1/3/10 - Roof Deck Insulation

In early December we had closed cell spray foam insulation applied to the roof, under the entry and bedroom bump-out which over hang the foundation, and on the rim joist. Although not the most environmentally friendly insulation it was a good choice for this roof. It not only provides high R value per inch, but creates an effective moisture barrier for our un-vented roof with big sky lights (always a leak potential).
